Be it lrnown that I, HARRY V17. l/ViLLrAisrs, a citizen of the United States, residing at Dayton, in the county o' Montgomery and State of Ohio, have invented certain new and useful improvements in Cooling ripparatus for Lard-Dispensing Machines, ot which the following is a speciiication.

rihis invention relates to a water circulating system for lard dispensing machines, such as is shown, and described in United States Letters Patent No. 1,068,153, granted to W. R. Mittendorf, July 22, i913. The machine or" the aforesaid patent is designed and constructed for dispensing lard in retail quantities from the container in which it is placed by the packer. It has been` found, owing to the variations in temperature that the lard becomes too soit in the summer months and too hard during the colder months ot the winter season, to be handled by the means shown and described in said Letters Patent. lln other words, the condition of the lard within the container must be neither too soit nor too hard in order to be properly acted upon by the means ein ployed in said patent for removing the lard from the container. lt is therefore the object of the present invention to provide a cooling circulating system around the lard in the container and the passage from the container to the point et discharge Yfrom the apparatus.

ln the accompanying drawings much only of the lard dispensing machine is shown to enable a description ot this cooling apparatus in connection therewith. lieferino; in general terms to the drawings, Figure l is a side elevation otl the body or upper portion of the machine in which the lard container is inclosed and the spiral conveyor which feeds the lard i'roin the container to the discharge spout. F 2 is a vertical sectional elevation on +he line 2 2 of Fig. l of the body of the dispensing inan chine or upper portion of the machine in which the lard container is inclosed, the lard container being shown in section also. Fig. 8 is a vertical section view on the line 3 3 of Fig. 4 of the lower portion of the body and the portion therebelow which houses the spiral conveyer. Fig. li is a horizontal sectional. view on the line 4 4 of Fig. l. Fig. 5 is a horizontal sectional view on the line 5 5 of Fig, 1. Fig. 6 is an elevation Specification of Letters Patent.

looking on the interior of the water jacket showing the water inlet and outlet. Parts of the two sides et the jaclret are broken away on each side of the hinges. Fig. 7 is zit-horizontal View on the line 7 7 ot Fig. 6. F tl is a detail View illustrating the feed disk.

ln a detailed description oi the invention similar reference characters indicate corre` spending parts in the several views of the drawings.

The lard vending machine in its entirety has not been illustrated in the accompanying draw-ings because many of the details thereof are not involved in the present irnprovernents. The stand upon which the lard container frame-work is supported is not shown, nor is the means for operating the pressure disk which removes the lard from the container shown, nor the ineans for operating the spiral conveyor which discharges it from the machine shown. All of these features as well as other elements peculiar to the lard dispensing machine are shown and described in the patent hereinbefore referred to. The portions of the ap paratus in which the lard is contained is what concerns us hereas it is with these portions the present improvements have to do. As shown in Fig. 2 the lard container l is supported in an inverted position on a bowl or lower receptacle 2, said bowl being sup ported on three or four legs 3 as may be desired. rihe pressure or feed disk 4 in the body oi? the lard within the container l. feeds the lard down into the howl 2 and from there the spiral conveyor 5, which lies within the bowl 2, i'ieeds it out through the discharge spout G into the delivery cup 3'?. T he pressure disk i is attached to a connecting rod 7 and this connecting rod and the spiral conveyer are both driven from the same source of power as is clearly shown and described in the patent hereinbefore referred to. The dislr 4 is enabled to cut its way through 100 the lard owing to the auger-like slot Q therein as shown in Fig. 8.

t will be understood that thewhole interior of the apparatus as shown in Figs. 2 and 3 is always full of lard. Thisis espe- 105 eially true of the howl 2 and the discharge spout 6. The container l, is discharged oi` its contents during the operation of the Ina-- chine but there is always some lard therein until the last portion is removed therefrom lio into the bowl or lower receptacle 2. As each lard container is emptied by the disk 4 a new full one is placed in the machine with the mouth down and the disk is driven through the lard therein until it reaches the bottom of the can, or the top when the can is in position as shown in Fig. 2, as is fully described in the patent hereinbefore referred to.

l will now proceed to describe the water circulating systems or passages which surround the lard in the body of the machine or container and also the lard in the bowl 2 around the screw conveyer, and in the discharge spout 6 and delivery cup 37. Referring to Figs. 1, 2 and 6, 8 designates the inlet pipe through which water passes under pressure from the source of supply, for example, the city main. The water suppliedy to the hood passes through a T or two-way fitting 15 which discharges on both sides into flexible pipes 9-9 which connect to nipples 10-10 that communicate with the lowermost water channel 11 in the hood parts. The hood,consists of two sections or parts A-B, each of semi-circular form. rlhe rear vertical edges thereof are shown in Fig. 6 to be united to bars 12 which lie on the exterior thereof. The ends 13 of the said bars turn out and receive a pipe 14 which forms the pivot of the hinges or parts 13. The front vertical edges of the hood come together when closed and are held closed by any suitable means such as a spring catch (not shown). lt will be understood that the members A-B of the hood open 'to permit the empty lard cans to be removed and lled ones placed in the machine. I have specified that the flexible pipes'9-9 enter the bottom water spaces or channels 11 in the hood members. From these bottom water channels the water passes upwardly into water channels 16, 17, 18. These water channels are formed by a series of partitions 19, it being understood that the hood members A and B areV formed each of two walls as shown in Fig. 2 between which the distance pieces orV partitions 19 are secured. The water passes from one channel to the other through passages 2O which are at opposite ends of the partitions, see Fig. 6 where two of such passages appear. When the upper channels 18-18 are filled the water passes out through flexible outlet pipes 21-21 which connect with nipples 22-22 in the upper portion of the inner walls of the hood members, see Fig..7. It will be understood that the pipes 9 and 21 are necessarily flexible on account of it being necessary to open and close the two members of the hood. The upper flexible pipes 21-21 connect with a Y-fitting 23 which connects with a down outlet pipe 24 which passes down through the pipe 14 which as hereinbefore stated forms the pivot for the hinges 13--13 of the lard in a proper state of firmness. rl`he bowl or lower receptacle 2 is partially maintained at the desired temperature through the Vconductivity of the metal. Around the margin 'of said bowl a water circulating channel 27 is formed. As hereinbefore specified the bowl 2 is always supplied with lard which is fed therefrom into the discharge spout 6. Referring to Fig. 6 the main water inlet pipe 8 continues above the T-fitting 15 in an extension 8. This extension 8 connects with the water circulating channel 27. The water from channel 27 circulates through a nipple 28 (Fig. 3) into a channel or water space 29, which entirely surrounds the discharge spout 6 which, it will be undertsood is always full of lard from the conveyer 5. The water in space 29, when it fills up, passes into a channel 3() along the lower side of the spout 6, and into a rectangular water channel 31 in the bottom of the bowl 2, shown in broken lines in Fig. 5. rlhe water enters the channel 31 from the channel 30 through a nipple 32, and the channel 31 exhausts through an outlet connection 33 that discharges into the'main waste pipe 25. The discharge cup 37 is hinged to the top of the spout 6 as is more fully disclosed in the patent hereinbefore referred to. It is swung around out of alinement with the spout to discharge its contents. rlhe said cup also has a water jacket or space 38 which receives the circulating water from the spout water space 29 through a flexible pipe connection 39. The space 38 discharges into the spout outlet channel 30 through a flexible pipe connection 40. From the foregoing description it will be seen that the parts containing the lard and the passages through which it is fedare wholly inclosed by cooling channels or spaces.

As hereinbefore stated the pressure disk 4 and the spiral conveyer 5 are driven by the same power. The power is conveyed directly to the conveyer by a crank handle 34 which is shown broken ofil in Fig. 3, and from thel shaft of the conveyer the power is conveyed through a chain 35 (which is also broken volf in Fig. 3) to the rod 7 through intervening drive mechanism which is fully disclosed in the'patent hereinbefore referred to.
